There was no "Z51" suspension in 93. There was a base suspension with fairly soft shocks, a base suspension with the Selective Ride Control (RPO FX3) adjustable shocks, and for coupes only there was RPO Z07 which was a performance suspension package with stiffer springs, larger sway bars and also had the FX3 adjustable shocks.
I found the ID tag in the console lid . I have the FE1 suspension. I just bought my car so the confusion was the shocks on all sites listed Bilstein HD or Bilstein for Z51 suspension in my 1993 Corvette. Going with the Bilstein HD's
Thanks for the input. One more question, can I put the stiffer leaf spring on if the Bilsteins do not stiffen the rear end ride. I put new KYB's on and I still had bounce in the rear. We checked the leaf spring and it looked fine so I have Bilsteins arriving tomorrow. I hope they will make for less bounce. Input appreciated.
Thanks,
